A border element arrangement includes two or more border elements abutting each other side-by-side. The elements have a frame provided with end bars and a structure connecting the end bars at least in the top part and bottom part of the frame, and disposed to be supported by the frame is a digital display that is capable of displaying a moving image. The display has one or more display panels. In both end bars is a recess, inside which the display is disposed at the point of the end bar.

The present disclosure discloses a method for making an ice surface of an ice rink and an ice rink including the ice surface. In the method, a salt solution is applied to an ice surface. The salt solution contains anions. A concentration of the anions is in a range from about 0.63 mmol/L to about 10 mmol/L. The anions in the salt solution are selected from the group consisting of chloride ions, nitrate ions, bromide ions, iodide ions, chlorate ions, perchlorate ions, thiocyanate ions, and any combination thereof. The ice surface is maintained at a temperature of about −4° C. to about 14° C. to naturally freeze the salt solution.

Inflatable skateboarding ramp with an inflatable base that gives shape to the ramp, a semi-rigid surface located on the upper face of the inflatable base with one or two entrance platforms, as well as a rolling area and means for fixing the semi-rigid surface and the inflatable base.

A connector for removably securing and vertically stacking perimeter components of a skating rink. The connector includes an elongated body extending a length from a first axial end to a second axial end along an axis thereof. The length is selected to span a height of at least two perimeter components. A first anchoring feature extends at least a portion of the length into or along a first lateral side of the elongated body. A second anchoring feature extends at least a portion of the length into or along a second lateral side of the elongated body.
